SPECIFICATION forming part 4of Letters Patent No; 312,815, dated February 2%, 1835.

` l Applicatifn Filed June 18, 1883. (No model.)

To all whom, it may concern/ Haven C. Pnnrriirr, citizens ol the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Machines for Opening and Cleaning Textile Fibers, of which the following is a specification.

Our invention relates to machines for opening and cleaning textile bers; and it consists in certain novel Icombinations ofthe parts of such machines, substantially as hereinafter described and claimed.

In theaccompanying drawings, Figure 1 is a cross-section of av beater provided with a perforated tubular shaft; Fig. 2, a longitudinal section of the saine and its drivingpulley; Fig. 3, the same as Fig. 1, With the addition of pipes or hollow guards inserted in the perforations; Fig. 4, a central longitudinal section of a part of the beater and of a pipe and a fan-blower; Fig. 5,k a partial side elevation of a lappercontaining such abeater.

A is `the frame of the lapper; B B, apronrolls; O, thevapron; I), an apron-side; E E', feed-rolls, F, a beatershaft; F', its arms; F2, its blades 5 F5, a driving-pulley secured to the beater-shaft, Aby means of which the beater' is caused to rotate by a belt from an overhead counter-shaft; G, the beater-grate; HH, lapcollecting wire cages; I I', drawing-rolls, J J J2, calender-rolls; K K', lap-rolls; L, rotary exhaustfan;r T T', exhaust-pipes to lead the air from the wire cages to the fan, all the above-named parts being of the usual construction and operation except the beater, which, instead of having, as usual, a solid shaft, has insteada hollow or tubular shaft,

F, which shaft has perforations or holes Fibe-y tween its arms Fl The object of these holes is to allow the air which enters the shaft at one or both ends to be thrown out by centrifugal foiuce when the shaft is revolved rapidl k llroimake the iiow of air stronger and more certain, there are pipes or hollow guards Ft, which proj ect from said holes F andare curved backward-that is, contrary to the direction of the rotation of the beater-so that the rotation of the beater Willthrow the air out with considerable force. The force with which the air is expelled through the holes is increased by a blast of air from a rotary blower, N, di- ',rected through a pipe, N', leading into one or both ends of the beater-shaft. Of course, if the air is blown into only one end of the beatershaft, the .other end of 4the shaft should be plugged up or closed.

The blower N is of any usual construction. The object of causing the air to stream out through the projections in the shaft is to better prevent the fibers from lodging on the ends of the beater-arms ,and on the blades of the beater, and also to better assist the passage of the Iibers from the beater to thelap-collecting cages, and to better aid to accomplish in a more satisfactory manner what is now done by the exhaust-fan L and pipes T T', which, by taking the air from the inside of the cages, cause the air to rush through the wire coverinto said cages and out through the exhaustpipes and fan-case into the usual dust-receptacles, and leaving the iibers upon the outer surfaces ofthe cages, which, by their revolution, form the fibers into asheet between them.

The beater, as heretofore used, by its rapid revolution, has a tendency to compress the air in front of the beater-blades, and to create a vacuumy behind the blades and at the center of the beater, and thereby to cause the fibers to circulate around with the beater, produc ing curling and stringing77 ofthe iibers-by of the ibers together. This curling and string ing is prevented by admitting suicient air to the middle of the beater in the manner hereinbeforey described. rlhe air is commonly ad mitted to the beater underneath or through the front beater-grates, and by the operation ofthe beater on the fibers the heavier refuse falls through the grates; but the inrushing air takes the lighter dust baci; into the machine and does not extract it from the iibers. By admitting air through the shaft of the beater, as herein described, this diiiiculty is obviated.

Instead of a pair of lap-collecting cages, a single cage with a roll, in` place of the other cage, ymay be used in the Well-known manner without departing from the spirit of-our invention, this single cage and auxiliary roll or stringing7 meaning a twisting and mattinging thereof into y'the same, carrying the dust IOO a pair of cages performing the same function, and we term either a set of lap-collecting cages. A

W'e claim as our inventionl. A beater provided with a hollow shaft having one or more perforations, said shaft being open at one or both ends, and means, substantially as described, for supplying a continuous current of air to said perforations through said hollow shaft, as and for the purpose specified.

2. The combination of the beater provided with a hollowr perforated shaft open at one or both ends, means, substantially as described, for supplying a continuous current of air to said perforations through said hollow shaft, and a set of lap-collecting cages, as and for the purpose specified. v

3. The combination of the beater provided with a hollow perforated shaft open at one or both ends, means,'substantially as described, for supplying a continuous current of air to said perforations through said hollow shaft,

terior of said shaft and open at their outer ends, and means for rotating said beater, as

and for the purpose specified.

`5. The combination of' a beater provided with a perforated hollow shaft and outwardlyextending pipes, the outer ends of said pipes being bent in a direction contrary to the di reetion ofthe rotation of said beater, and means for rotating said beater, as and for the pur- 4o 'pose specified.

Correction in Letters Patent No. 312,815.

1t is hereby eertilied that in Letters Patent No. 312,815, grunted February 24, [$35, upon the application of Alfred Clarke anni Haven U. Perhmn, of Lowell, Mussziohusetts, for an improvement in Machines for Opening' mid Cleaning Cotton and other Fibers, an error appears in the printed specification requiring the following correction, viz: In line 53, page l, the word is between the words holes and increased should read may be; and that, the Letters Patent should be rend with this correction therein to make it conform to the record ofthe cose in the Potent Office.
